Jack mount corner accessories?

[The salt]

Anyone know where to find accessory brackets for the corner jack mounts, or who makes them? I've seen some of these mounts for antennas, shovels, axes, High-lift jacks, etc. I don't know if I am phrasing it correct or not. Seems like a great spot for adding gear without having to drill more/extra holes in the camper. Thanks in advance.

I tried throwing some Quick Fist grips on… seems to hold ok. I would rather have some brackets made for a specific application though. I’d hate to lose a tool on the road/trail.
